A question about Boxster 01 overflow pipe.

As Monty said, the coolant overflow pipe typically empties onto the ground in front of the right rear wheel. Coolant behind the right rear wheel is generally more indicative of a coolant reservoir leak but you said that you just replaced the reservoir so it must be coming from another source.

Priority #1 is to get under the car and trace the wetness back to the source (coolant overflow pipe or something else). Let us know what you find.

Well, anything is possible but its more likely that the engine is getting hot because either the coolant is still leaking somewhere or there is still air in the coolant system. As Monty suggested, refill and do a really good purge to see if that helps.

Its hard to say yes or no because it depends on the root cause of the issue. For example, if the cause is a leaky aftermarket coolant tank (despite being new) then replacing the engine won't help. But if its a cracked cylinder or a cracked head/head gasket, then yes. With all of that being said, it shouldn't take an engine replacement to get to the source of your coolant problem. Once you know the root cause, the path forward will be pretty clear.

Great job thus far, the car looks fantastic and those are my favorite stock Boxster wheels.
